GTE Internetworking and Dialpad.com announce alliance for free PC-to-Phone call service in U.S.

Dialpad.com makes it simple to dial anyone, anywhere over GTE's private Voice-over-IP telephony network.

GENEVA, SWITZERLAND - GTE Internetworking today announced a wholesale agreement with Dialpad.com, Inc., a Silicon Valley-based, next-generation Internet telecommunications company. The agreement calls for Dialpad.com to utilize GTE's recently launched private, high quality Voice-over-IP (VoIP) network throughout the United States as the infrastructure for Dialpad.com's free PC-to-Phone service aimed at consumer and small business markets. Available on Oct. 18, 1999, the service will allow users to place free phone calls to any phone number in the continental United States using Dialpad.com on a standard PC connected to the Internet.

Voice over IP (VoIP) enables voice conversations to travel over IP data networks, providing savings and convenience from the desktop. Dialpad.com's new service will transport traffic over GTE Internetworking's managed IP telephony network, which is built on the company's Global Network Infrastructure (GNI) - not over the public Internet - providing high quality. GTE's GNI is a state-of-the-art, private fiber backbone spanning 17,000 miles in the United States alone, with high capacity reach worldwide.

"Dialpad.com's Internet business model, combined with their Java-based micro-application architecture, is a prime example of the rapid changes IP telephony is bringing to the telecommunications market. This is an extremely exciting relationship because it demonstrates how our open standards-based, high quality VoIP network can help our partners quickly deploy new customer-centric value-added services," said Paul R. Gudonis, president of GTE Internetworking, a unit of GTE Corporation (NYSE: GTE.)

Dialpad.com's innovative technology is helping to expand the role of the personal computer as the ubiquitous communications platform. With the introduction of Dialpad.com, Internet users can add free phone call service to other desktop communication tools.

"Dialpad.com takes an entirely different approach by giving Internet users the ability to make free phone calls, around the corner, or across the country," said Dr. Hyunduk Ahn, Dialpad.com's president and CEO. "Our unique open standards-based technology works with more than 95% of today's PC's. All a user needs to start making free phone calls is a 33.6k or greater web connection and a sound card. Best of all, users can talk as long as they'd like," Ahn added.

Dialpad.com has a patent-pending, distributed H.323 architecture. The Dialpad.com desktop application is a small, 156k Java applet that is engaged when a user's account is accessed. The Java-based Dialpad.com applet provides simplicity, ease of installation, and convenience of use.
